WhatsApp on Tuesday announced a new feature that will allow users to save contacts within the app. That means that even if you lose your phone or link a new device to your primary number, you will see all your contacts stored within WhatsApp’s cloud storage.

Until now, WhatsApp relied on your phone’s contact book to sync contacts. If a new person messaged you on the app, and you wanted to save their details, the information would be stored locally on your device.

The new feature, rolling out soon, lets you store contacts on any device, including WhatsApp for the web and Windows. You can choose to sync contacts saved within WhatsApp to your phone, as well.

Last year, the company began allowing users to log into two WhatsApp accounts on one device. Saving contacts linked to one WhatsApp account is handy if you want to keep personal and business contacts separate. Plus, if you share the device with others, you can maintain your own contact list linked to your number.

WhatsApp said it developed a new encrypted storage system called Identity Proof Linked Storage (IPLS) to enable secure contact saving. When users save a contact, the system generates an encryption key on the device. The retrieval is based on the client authenticating its primary device identity.
